Top sci-fi series to stream on OTT: 'Severance', 'Andor' and more

Science fiction television has been delivering some of the most ambitious, unsettling, and genuinely inventive storytelling the genre has seen in years. From corporate dystopias to alien invasions to post-apocalyptic scenes, these are the shows that proved science fiction is not just about the future but about every uncomfortable truth we are already living with. Here are 7 series worth adding to your watchlist.

'Severance' follows employees at Lumon Industries who have undergone a procedure that surgically divides their work and personal memories, making them two entirely separate people who share the same body but know nothing of each other's lives. Adam Scott, Patricia Arquette, John Turturro, and Britt Lower lead the cast, with the show created by Dan Erickson and directed by Ben Stiller, bringing the deeply unsettling corporate dystopia to life with extraordinary precision. This psychological sci-fi thriller is available for streaming on Apple TV+.

'Andor' follows Diego Luna's Cassian Andor in the years before 'Rogue One' as the Rebel Alliance takes its first dangerous, uncertain shape against the Empire. Stellan Skarsgard and Genevieve O'Reilly feature in a cast guided by creator Tony Gilroy, who gives the political and moral dimensions of the rebellion a weight and complexity the Star Wars universe had never quite attempted before. For fans of grounded, intelligent political sci-fi, this one is available for streaming on JioHotstar.

'Alien: Earth' is set before the events of the original film and follows Sydney Chandler and Alex Lawther as survivors on a future Earth already struggling under corporate colonisation before something far worse arrives. Creator Noah Hawley brings the claustrophobic dread and creature design that defined the films while expanding the mythology in genuinely frightening new directions. For fans of the franchise who want more of that signature terror, this series streams on JioHotstar and Hulu.

'The Eternaut' stars Ricardo Darín as a man navigating Buenos Aires after a mysterious toxic snowfall wipes out most of the population, based on the legendary Argentine graphic novel. Rooted in a specifically South American political consciousness and directed by Hernán Cifuentes, the show has a depth and urgency that sets it apart from the genre's more familiar post-apocalyptic offerings. This Argentine sci-fi gem is streaming on Netflix.

This Korean sci-fi thriller stars Suzy and Um Ki-joon in a tense, high-concept story built around an AI system that can predict disasters before they happen, exploring what happens when the people tasked with acting on those predictions begin to question whether preventing the future is always the right thing to do. Director Jang Hang-jun handles the show's ethical dimensions with intelligence and restraint, never letting the philosophical weight crush the propulsive thriller underneath. Fans of cerebral, morally complex sci-fi will find it on Netflix.

'Revival' stars Wyatt Russell and Camryn Manheim in a story set in a small Wisconsin town where the recently dead have inexplicably returned to life, not as monsters but as themselves. Creator Andrew Hinderaker is less interested in horror than in the grief, legal chaos, and moral confusion that would actually follow such an event, giving it a grounded human focus that sets it apart from the genre. This quietly unsettling sci-fi drama is on Peacock.

'Murderbot' stars Alexander Skarsgard as a part-human, part-robot security unit that has secretly hacked its own governor module and now just wants to watch TV serials while reluctantly protecting the humans in its care, based on Martha Wells' beloved novella series. Creator Chris Overton captures the character's sardonic interiority and deep social anxiety with a wit that makes it one of the most distinctive sci-fi comedies in recent memory. For fans of genre television with a genuinely original voice it is on Apple TV+.
